Science
Mechanism of Action
This extract functions as a potent antioxidant, utilizing its rich content of flavonoids and Vitamin C to scavenge free radicals and neutralize oxidative stress induced by environmental factors like pollution and UV radiation. Its essential oil components contribute mild antiseptic and purifying properties, assisting in clarifying blemish-prone skin. It offers soothing and anti-inflammatory benefits, effectively calming and conditioning irritated skin. Foeniculum Vulgare Leaf Extract is also suggested to promote toning and firmness by inhibiting elastase, an enzyme responsible for elastin degradation, thereby helping to preserve skin structure. Additionally, it conditions the skin, enhancing softness and smoothness, and supports the natural moisture barrier by regulating hydration.

Key findings
- 01 Creams containing 1% and 2% of fennel extract showed antihirsutism activity, with 2% being more effective than 1% in a double-blind study.
